satellite coupling 中文意思是什麼
satellite coupling
解釋
衛星接合-
Across the rigid - flexible coupling dynamic analysis, we acquired the coupled effects between the three - dimensional attitude motion of the satellite and the flexible vibration of the antenna ' s supporting beam, and got the dynamic behaviors of the system. and we found the change pattern of the antenna ' s structure parameters, which decide the system ' s connatural characteristic and its dynamic response
通過對衛星?天線形成的剛柔耦合系統進行動力學分析，獲得了衛星的剛體運動與天線的彈性振動之間的耦合影響規律及其真實的動力學行為，得到了天線結構參數對衛星?天線系統的固有特性及其動力學響應的影響規律，為衛星姿態控制和天線結構優化設計奠定了基礎。 -
Since previous studies have focused on theoretical research, space magnetic environment will be affected by many known or unknown factor, such as the electronic devices on satellite would product magnetism by currents through, and this would coupling the earth magnetism
由於以往的研究多集中在理論研究上，空間磁環境還會受到很多已知或未知因素的干擾，如星上電子器件由於電流通過而產生的磁場對地磁場的耦合等。 -
The natural frequencies of the antenna are low and dense because of its large dimension, light mass and large flexibility. dynamic analysis is needed to avoid the coupling motion between the satellite and the antenna. firstly the thesis sets up the dynamics model of the satellite - antenna system based on the hybrid coordinates
由於天線尺寸大、質量輕、柔性大，天線的固有頻率很低且十分密集，為避免天線與衛星的調姿運動產生不良耦合影響，需對大型可展開天線與衛星系統進行剛柔耦合動力學分析，從而為天線的結構設計提供可靠的理論依據。 -
Secondly, the performance of the acousto - optic steering system is deteriorated as a result of the coupling because of nonlinear of quadrant detector and the pointing error introduced by satellite platform vibration. for this problem, this paper introduces the model reference adaptive control system, and presents the perfect model. the model reference adaptive controller is designed to force the output of the acousto - optic steering system following the output of the perfect model to improve the system performance
其次，針對聲光偏轉系統由於器件的非線性造成的耦合和平臺振動造成的指向誤差導致系統性能惡化問題，引入了模型參考自適應控制系統，提出了理想的模型，設計了模型參考自適應控制器，強迫性能惡化的聲光偏轉系統的輸出跟隨理想模型的輸出，使其性能改善，利用超穩定性理論確定自適應參數以保證系統的穩定性。
